<h1>EVALUATION OF BURNING CHARACTERISTICS OF VARIOUS KINDS OF BIOMASS</h1><br>
Biomass fuels have high oxygen web content and high natural volatiles, which will certainly create big quantities of volatile gases throughout the burning stage. Both the vapor stage burning of the volatiles released throughout the fuel home heating pyrolysis procedure takes place, as well as strong multiphase burning occurs during the coke oxidation procedure. The volatiles melt very promptly, almost the exact same price as the volatiles, and also the oxidation of coke is much slower. Biomass combustion can be divided into 3 phases, the first stage is the dehydration stage, the second stage is the unstable evaluation combustion stage, and also the third phase is the coke burning stage.



BURNING QUALITIES OF BIOMASS PELLETS AT DIFFERENT HOME HEATING PRICES.

The combustion-supporting gas is a combination of oxygen and also nitrogen with an oxygen content of 20%. The TG as well as DSC curves of biomass particles melting at different home heating rates reveal that the heating rate has a higher influence on the combustion of biomass particles. As the rate of temperature level increase increases, the burnout temperature levels of different sorts of biomass bits enhance. The last residue top quality of the combustion of biomass fragments also enhances with the boost of heating price, yet the rise is not evident. When the heating price is readied to 20 ° C · min-1, the final deposit top quality of biomass bits is shed. maximum. The rise in the rate of temperature boost also enhances the price of weight reduction of the biomass. The rate of weight reduction when the heating price is 30 ° C · min-1 is a lot more than the other 2 type of heating rate, and also the TG contour is smoother than the various other 2.



Combustion features of biomass pellets in different oxygen contents.


Various oxygen levels have a considerable result on the TG and DSC curves of biomass pellet burning.



The oxygen material in the combustion-supporting gas is enhancing, so that the burn-out temperatures of various kinds of biomass fragments are minimized. The results of the last deposit high quality on the combustion of different kinds of biomass bits are not the exact same. The change in oxygen content has little result on the final residue quality of the sawdust fragments and also the rice husk particles, and also the final residue top quality of the two biomass particles stays considerably unmodified. For shavings particles, the last mass of the melt is 20% at the oxygen material. As the oxygen content of the straw granules continues to enhance, the last deposit quality likewise enhances, reaching a maximum at an oxygen material of 33%.



The oxygen material has a significant impact on the DSC contour of the biomass particles. The other oxygen web content of combustion-supporting gas is boosting, as well as the exothermic optimal of various sort of biomass fragments is also enhancing. When biomass pellet making machine is 33%, the exothermic optimal of biomass fragment combustion reaches the maximum. The temperature level at which the exothermic peak gets to the optimum likewise reduces with the rise of oxygen web content, and also the temperature is the lowest when the oxygen material is 33%.



Contrast of burning characteristics of refined biomass pellets and also unprocessed biomass.

Combustion setting: The home heating price is 20 ° C · minutes -1, as well as the oxygen web content of the combustion-supporting gas is 20%. It can be known from the TG as well as DSC curves of biomass burning of different handling innovations, whether the biomass is refined or not, as well as the burning particular curve is clearly various.




The TG curves of processed rice husks and unprocessed rice husks are significantly different. The last residue high quality of the refined rice husk is a lot smaller sized than that of the unprocessed rice husk, and also the melted temperature level of the processed sawdust is additionally greater than that of the unrefined sawdust. The distinction in the DSC contour of rice husk is likewise apparent. Richi machine of the unrefined sawdust reveals 2 distinctive exothermic heights, and the initial exothermic optimal and the 2nd exothermic peak are rather different. After the handling and also creating procedure, the sawdust DSC contour has 2 similar exothermic heights.
